Tutorial: Adafruit 1-Wire Thermocouple Amplifier – MAX31850K

Tutorial: Adafruit 1-Wire Thermocouple Amplifier – MAX31850K. Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. So far we’ve carried the very nice MAX31855 which is an SPI interface thermocouple amplifier. The ‘855 is great but if you have a lot of thermocouples to measure it isn’t terribly easy to use. That’s why we are also carrying the new ‘850 model from Maxim – it’s a “1-Wire” thermocouple amp which can have any number of breakouts on a single shared I/O line.
